update Herring Gull section ORG

Post by marsmuusse » Thu Jan 17, 2013 8:47 pm

I've uploaded about 25 immature Herrings (3cy, 4cy, 5cy), photographed yesterday at Katwijk beach, which is less than 10 minutes. Sunny conditions and -12 at night.
See:

Adults will follow later this week.

Another update for February (about 50 flying birds, all plumages) and an update for March, flying birds in all plumages, about 45 birds.
See 2CY March, 3CY March, etc section for Herring Gull:

Another update for Herring Gulls: 18 flying 2CY birds to show moult scores for early July. Most common pattern P5/P8, next P4/P7, so most birds now 5 or 4 fully grown inner primaries and still with P8-P10 juvenile or P7-P10 juvenile. Below, an image that represent the slightly advanced birds, which have shed tail feathers. See:
http://www.gull-research.org/hg/HG2CY07.htm

Other plumages and birds from June to follow soon... Hope you'll enjoy!

There was a gap in open wing Herring Gulls in April. Last weeks nice weather was of great help: I've added 70 flying 2CY and about 20 flying 3CY Herrings for April, other plumages will follow soon.
See: http://www.gull-research.org/hg/HG2CY04.htm


Unfortunately, all unringed birds, but hope the variation in Herring Gull is well covered and illustrated...

Some sub-adult and adults added as well for April:

Including yellow-legged birds from Finland (many thanks to Petteri!!!) And some birds from Katwijk beach, the Netherlands near my house:

These yellow-legged gulls images by Petteri made me decide it is time to add the Alula 1998 article by Lars Jonsson to the site, see the same link above...
